Hi,I have an 11 year old daughter who noticed yesterday that she had some dark maroon or blackish blood in her stool when she went and had a bowel movement. She was very scared and the next time that she went to the bathroom and peed there was a little again which appeared to come from her rectum. At first I thought that maybe she was getting her period for the first time however it seems to be happening just in the last 2 days and only when she has a bowel movement? Is she too young to have an ulcer? She is a BIG worrier and has been worrying lately lots about somethings happening in her life, since she is such a big worrier could she be worrying herself right into the ulcer? Can a stomach ulcer cause bleeding in your stool? Would appreciate any thoughts that anyone might have. Worried Mom!!!
